Mediators: These are the variables that **mediate the path between 2 variables(referred to treatment and outcome)

Mediators are an essential part of the causal Paths. Conditioning on mediators blocks the causal paths between the treatment and outcome.

Mediation analysis is the analysis of understanding the front door paths from treatment to the outcome.
